That has been the case since MPLS debuted.

Hey Sabri,
Eventually they have implemented everything ;-)
Arista was a really special case, routing stack they acquired (NextHop) had no
mpls (quite some time ago), 90% of their revenue was coming from IP only
networks.

Plane IP underlay works real well, I’m yet to see tangible proof of TE in DC
(outside of niche HPC/IB cases).
SR in DC - with overlay starting on the host SR-MPLSoUDP(RFC8663) is a perfect
representation of a working technology that works in IP environment as well as
allows end2end programming

Marketing, not fundamentals. DC people

There’s no modern silicon that doesn’t support MPLS (and is capable of imposing
at least 3 labels). There’s 0 additional price for vendors to enable MPLS on
their devices. The rest is subject to vendors’ licensing and is completely
artificial.
